The frequency and the intensity of a beam of light falling on the surface of a photoelectric material are increased by a factor of two. This will

A

Increase the maximum kinetic energy of the photoelectrons, as well as photoelectric current by a factor of two

B

Increase the maximum kinetic energy of the photoelectrons and would increase the photo electric current by a factor of two

C

Increase the maximum kinetic energy of the photoelectrons by a factor of two and will have no effect on the magnitude of the photo electrons by a factor of two and will have no effect on the magnitude of the photoelectric current produced

D

No produce any effect on the kinetic energy of the emitted electrons but will increase the photoelectric current by a factor of two.
